Solar Grid Storage has developed an energy storage system for solar power that not only powers the building and stores enough power for 4 hours, the local grid can use it to store or discharge electricity. Â Wow. This is a game-changer. Install enough systems like this and distributed energy becomes a reality everywhere.

The systems are installed and maintained by Solar Grid Storage and are leased to the end users. Utilities also pay the company because the systems help balance supply and demand, which is always crucial, but even more so with renewable energy, since it fluctuates in output.

This is the future of power. Microgrids and local power as well as gigawatt plants. Currently only one major utility allows this. Too many of the rest, with a few exceptions like Duke Power, are troglodytes who will change or die. This technology can’t be stopped.

Solar Grid Storage develops battery energy storage systems co-located with PV systems but separately owned and maintained by Solar Grid Storage. Our solution eliminates the need for PV developers to purchase a solar inverter, reducing installation costs and offering new benefits to the host. Solar Grid Storage finances the storage asset through revenues derived from multiple stakeholders. These revenues come from grid support markets that pay Solar Grid Storage to dispatch assets to maintain grid stability, and a series of new benefits, such as host emergency backup services, demand reduction, and peak shaving.

California’s push to 33% renewable energy by 2020 requires vastly more energy storage. In a first step, the state is requiring 1.3 GW of storage by utilities, customers, and third parties, also by 2020. Hmm, the plan seems mighty convoluted to me, imposes more regulation in a state already overburdened with rules, and 1.3 GW isn’t really all that much. However, due to the unpredictability of renewable energy generation, stored energy is absolutely needed.

[The California Public Utility Commissions seeks] to establish a regulatory regime in which utilities, third-party storage providers, and even customer-owned storage assets can play an integrated role. Those include rules that would limit utilities from owning more than 50 percent of the total amount of energy storage to be procured across the three “grid domains” of transmission, distribution, and customer-located storage.

This wind power storage was done with help from government grants and I say Yes to that use of taxpayer money. Storage is crucial if we are to transition to renewable energy on a massive scale. This wind power with battery storage installation is showing us how it can be done.

North Carolina-based Duke Energy just flipped the switch on what the company claims is the world’s largest battery power storage system. Situated at their Notrees wind farm in western Texas, the $44 million, 36-megawatt facility utilizes cutting-edge technologies to provide storage for—and therefore a steady supply of power from—the 153-megawatt renewable energy plant which supplies electricity to Walmart.

The flywheel system is already operating at 90% capacity in New York. Flywheels store power as kinetic energy and can release it instantly, This makes them highly useful for balancing out grid fluctuations.
